Product Description:
The KSM01.2B-061C-35N-S1-HG0-SE-NN-D7-NN-FW belongs to the KSM Motor Integrated Servo Drives series produced by Bosch Rexroth Indramat. By combining a servo motor and drive electronics in one housing, the unit simplifies cabinet layouts and shortens cable runs in modular automation. It is intended for decentralized positioning or speed control tasks on production lines where compact motion nodes reduce wiring effort and free panel space for other equipment. Mounting the drive electronics directly on the motor also keeps the power stage close to the load, which supports responsive axis control in distributed machine sections.
A single power and signal interface uses a Hybrid Connector, reducing the number of separate cable connections to the unit. Heat is removed through natural convection, so no fans or liquid circuits are required, and the enclosure can operate quietly in clean zones. The internal DC link is rated for DC 750 V, matching common bus voltages supplied by central rectifier units. Feedback is handled through a Hiperface optical encoder that generates 128 signal periods per mechanical revolution, allowing the controller to interpolate high-resolution position data. Motion commands and diagnostics are exchanged over SERCOS 2 (RS-422), enabling deterministic cyclic communication with other drives and PLCs on the ring.
Absolute position is referenced in a single-turn format, which suits axes that return to a home position after startup. The output uses a plain shaft, supporting clamp or friction couplings in tight assemblies, and a shaft seal is fitted to limit lubricant migration. The motor uses frame size 061 with length code C, and it is built as Standard version 2. The unit has the Basic performance level and no integrated safety option. It also comes without a holding brake, so vertical loads may require external holding hardware. Electromagnetic behavior is set by winding code 35, so the control system can be matched to the proper current and speed limits for the application.
